Interesting. I wonder what the benefit of that is. I guess maybe spreading the fuel burn across times when they are and aren't in motion? Maybe it's also quieter?

I believe it’s mostly because it allows you to use electric motors mounted on swiveling pods under the water line. The same thing with mechanical propulsion is tricky because of leaky shaft connections.

But apparently there are more advantages:

You can think of it as an electric transmission instead of mechanical gears.
